intellij-elm

• fixed type checker bugs (#117)
• improved Find Usages results (#118)

• Added 'Parameter Info' feature (#111)
• Fixed bug when loading test-dependencies that don't exist (#115)
• Fixed bug where name shadowing was marked as an error in Elm 0.18 (#116)

Two big new features in this release:

1. Type inference and type checking
2. Support for multiple Elm projects within the same IntelliJ project

Type Inference and Type Checking

Thanks to an epic contribution by @ajalt, the plugin can now perform type inference on arbitrary expressions in your program. Press ctrl-shift-p to display the inferred type of the expression under the cursor/caret.

The plugin also performs type checking, marking incompatible types in red.

There are 2 limitations to the type system as currently implemented:

1. it does not work if a function is missing a type annotation (typically not a problem)
2. it does not work if type variables (such as List a or Maybe a are involved)

We hope to remove the type variable limitation in the future.

Support for Multiple Elm Projects

You can now attach multiple elm.json (or elm-package.json) files to the same IntelliJ project. This allows the plugin to understand the structure of your Elm code and provide accurate code completion and go-to-declaration.
